The story of the word

For most of antiquity ἀστρολογία and ἀστρονομία meant roughly the same thing, and the man who wrote the standard ancient handbook of planetary motion, Ptolemy, also wrote the standard handbook of horoscopes. The two words split only in the seventeenth century, one keeping the mathematics and the other keeping the predictions. Chaucer's astrology is mostly what we would now call astronomy.
